The use of renewable energy sources raises the demand of fast and flexible storage techniques as well as fast power availability. A promising storage approach is the production of hydrogen and oxygen by electrolysis, which could be burned under humidified, stoichiometric conditions in a steam cycle. In this way the gases are re-electrified to provide balancing of renewable energy production or spinning network reserves. The current paper investigates the swirl-stabilized combustion of hydrogen and oxygen. The burner flow field and flame types are assessed using water tunnel PIV and OH* imaging in a combustion test rig. Parameter studies regarding the swirl intensity and thermal power are conducted.
